莒縣機械密封利用(yong)(yong)機(ji)械(xie)方式(shi)傳(chuan)遞(di)動(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)工程中(zhong)應(ying)用(yong)(yong)非常(chang)廣泛，有(you)(you)多種形式(shi)，主要包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)動(dong)(dong)(dong)(dong)和螺(luo)旋傳(chuan)動(dong)(dong)(dong)(dong)等。齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)能(neng)(neng)夠用(yong)(yong)于大(da)功率的(de)(de)場(chang)(chang)合(he)，傳(chuan)動(dong)(dong)(dong)(dong)比(bi)準(zhun)確，但一般(ban)要求較高的(de)(de)制造精(jing)度和安裝(zhuang)精(jing)度。還有(you)(you)一類是(shi)靠機(ji)件間的(de)(de)摩(mo)擦(ca)力傳(chuan)遞(di)動(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)的(de)(de)摩(mo)擦(ca)傳(chuan)動(dong)(dong)(dong)(dong)，包(bao)括帶傳(chuan)動(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)動(dong)(dong)(dong)(dong)和摩(mo)擦(ca)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)動(dong)(dong)(dong)(dong)容(rong)易實現無(wu)級(ji)變速，可以適應(ying)軸間距較大(da)的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而過載(zai)打滑還能(neng)(neng)起到(dao)緩沖和保(bao)護傳(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)作用(yong)(yong)，但這種傳(chuan)動(dong)(dong)(dong)(dong)一般(ban)不能(neng)(neng)用(yong)(yong)于大(da)功率的(de)(de)場(chang)(chang)合(he)，也不能(neng)(neng)保(bao)證準(zhun)確的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是莒縣機械密封的(de)更換工作大同小異，首先拆(chai)前需(xu)確認(ren)電機處于檢修狀態，擰下(xia)加油(you)螺塞，用(yong)吸管(guan)把(ba)密(mi)封座腔(qiang)內的(de)潤滑油(you)吸出。準備好放置泵零件(jian)的(de)工作臺及拆(chai)裝工具，切勿任意亂放亂用(yong)，避免碰壞泵的(de)零部件(jian)。

　　拆(chai)對分式(shi)聯軸(zhou)器(qi)：先把聯軸(zhou)器(qi)的固定(ding)內六角螺(luo)(luo)釘擰下來(lai)，再輕輕把聯軸(zhou)器(qi)的一半(ban)從軸(zhou)上慢慢拉下，注意不要(yao)掉了(le)，再用(yong)梅花(hua)扳手擰下泵軸(zhou)吊(diao)緊螺(luo)(luo)栓和(he)擋塊，讓葉輪慢慢下沉至泵體，然(ran)后(hou)拆(chai)下另外一半(ban)聯軸(zhou)器(qi)，拿下泵軸(zhou)擋圈(quan)。

　　拆卸莒縣機械密封：抓住密封彈簧順著泵軸(zhou)往上提(ti)，就能拆下來(lai)了。

　　拆卸(xie)并(bing)清洗軸(zhou)承(cheng)(cheng)座(zuo)：先(xian)輕輕松動一下軸(zhou)承(cheng)(cheng)座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)承(cheng)(cheng)座(zuo)，并(bing)且沿著(zhu)泵軸(zhou)往上(shang)提而卸(xie)下，再用(yong)噴氣燃料清洗軸(zhou)承(cheng)(cheng)及座(zuo)，裝前晾干并(bing)涂抹(mo)少(shao)許20號機械油用(yong)來潤滑(hua)保護。

　　拆密封座(zuo)：擰下密封座(zuo)壓緊(jin)螺母，輕輕卸下密封座(zuo)并清洗。

　　莒縣機械密封裝配(pei)：在(zai)動(dong)(dong)、靜(jing)環(huan)(huan)鏡面上(shang)涂一層潔(jie)凈的(de)20號(hao)潤(run)(run)滑(hua)油，導軸(zhou)承座也(ye)抹(mo)上(shang)潤(run)(run)滑(hua)油，先把靜(jing)環(huan)(huan)輕輕定位(wei)裝入(ru)導軸(zhou)承座，再在(zai)泵軸(zhou)上(shang)抹(mo)上(shang)潤(run)(run)滑(hua)油，把動(dong)(dong)環(huan)(huan)部(bu)分輕輕裝入(ru)泵軸(zhou)上(shang)，用(yong)手輕推密(mi)封環(huan)(huan)應能伸縮自如，注(zhu)意動(dong)(dong)、靜(jing)環(huan)(huan)部(bu)分的(de)防(fang)轉部(bu)位(wei)需裝配(pei)到(dao)位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)：在電機軸(zhou)頭上裝(zhuang)上擋(dang)圈(quan)，裝(zhuang)上一半聯(lian)軸(zhou)器(qi)(qi)，再在泵軸(zhou)端和聯(lian)軸(zhou)器(qi)(qi)槽內裝(zhuang)上擋(dang)塊并(bing)用梅花扳手擰緊螺栓；再裝(zhuang)上另(ling)一半聯(lian)軸(zhou)器(qi)(qi)擰上內六角螺釘。安裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)正確的檢查要(yao)求(qiu)：對(dui)分式聯(lian)軸(zhou)器(qi)(qi)上下間隙需要(yao)均勻，用手盤動聯(lian)軸(zhou)器(qi)(qi)幾圈(quan)檢查轉動的靈活(huo)性。

　　裝(zhuang)(zhuang)(zhuang)密封(feng)(feng)(feng)座：先將密封(feng)(feng)(feng)座裝(zhuang)(zhuang)(zhuang)入橡膠油封(feng)(feng)(feng)，再(zai)把(ba)密封(feng)(feng)(feng)座裝(zhuang)(zhuang)(zhuang)入泵(beng)蓋(gai)(gai)并壓(ya)在(zai)(zai)軸承座上(shang)，擰緊(jin)(jin)螺(luo)母，確保所有(you)安裝(zhuang)(zhuang)(zhuang)螺(luo)釘(ding)(ding)緊(jin)(jin)固(gu)(gu)。當安裝(zhuang)(zhuang)(zhuang)螺(luo)釘(ding)(ding)被用(yong)作密封(feng)(feng)(feng)與軸之間(jian)(jian)(jian)的驅動時(shi)，軸應(ying)打埋(mai)頭孔(kong)來加固(gu)(gu)連接，緊(jin)(jin)固(gu)(gu)壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)應(ying)該平(ping)穩緊(jin)(jin)固(gu)(gu)，并且不要使(shi)壓(ya)蓋(gai)(gai)受彈力。在(zai)(zai)可能(neng)的地方使(shi)用(yong)4個以上(shang)螺(luo)釘(ding)(ding)的等間(jian)(jian)(jian)距(ju)壓(ya)蓋(gai)(gai)，緊(jin)(jin)固(gu)(gu)壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)，用(yong)塞(sai)尺檢查(cha)軸與壓(ya)蓋(gai)(gai)之間(jian)(jian)(jian)的間(jian)(jian)(jian)隙，這在(zai)(zai)密封(feng)(feng)(feng)腔對壓(ya)蓋(gai)(gai)不導向(xiang)時(shi)，顯得特別重要，因為壓(ya)蓋(gai)(gai)必須對中(zhong)。
